Subscribe to Events

To subscribe to events from a device, connect to the MQTT API and subscribe it to the events topic for that device.

To subscribe to all events the MQTT topic is: devices/{device.id}/events/+

To subscribe to a specific event the MQTT topic is: devices/{device.id}/events/{event.name}

Replace {device.id} with your device ID (should begin with dev_) and {event.name} with the name of the event you wish to subscribe to.

Example Code

Subscribe to all events using the Wia SDK

// Create an instance of Wia // Replace 'd_sk_abcdef' with your device secret key var wia = require('wia')('d_sk_abcdef'); // Subscribe to all events for a device // Replace 'dev_abc123' with your device ID wia.events.subscribe({ device: 'dev_abc123' }, function(event) { console.log(event); }); // Connect to the MQTT API wia.stream.connect();

Subscribe to only temperature events using the Wia SDK

// Create an instance of Wia // Replace 'd_sk_abcdef' with your device secret key var wia = require('wia')('d_sk_abcdef'); // Subscribe to just 'temperature' events for a device // Replace 'dev_abc123' with your device ID wia.events.subscribe({ device: 'dev_abc123', name: 'temperature' }, function(event) { console.log(event); }); // Connect to the MQTT API wia.stream.connect();
